Keeping EVs Reliable: What Ongoing Checks Can Reveal
Electric vehicles (EVs) are rapidly becoming a common sight on UK roads, praised for their quiet operation, lower running costs, and eco-friendly credentials.
But while EVs have fewer moving parts than traditional petrol or diesel cars, that doesn’t mean they’re maintenance-free. Reliability still depends on regular checks—and knowing what to look for can make all the difference.
From battery performance to braking systems and tyre wear, ongoing inspections help EV drivers catch potential issues early, optimise vehicle health, and ensure long-term performance. Here’s what regular checks can reveal and why staying proactive is key to keeping your electric car on the road.
The Unique Maintenance Needs of EVs
EVs don’t require oil changes or exhaust system repairs, but they do come with their own set of components that demand attention. Electrical systems, regenerative brakes, cooling systems, and charging equipment all benefit from routine assessments.
Unlike older combustion-engine vehicles, many EV issues are detected through software diagnostics and system updates—yet physical wear and tear still matters.
What Should You Check to Support EV Reliability?
1. Battery Health and Performance
The high-voltage battery is the heart of your EV. Monitoring its condition over time can highlight problems such as reduced range or irregular charging.
Ongoing diagnostics can reveal:
- State of charge (SoC) inconsistencies
- Heat management system faults
- Early signs of capacity degradation
These insights help extend battery life and avoid unexpected breakdowns or range anxiety.
2. Brake System Condition
EVs use regenerative braking, which recaptures energy during deceleration and reduces wear on brake pads. However, traditional brakes are still essential—especially in emergencies.
Checks can uncover:
- Uneven brake wear from lack of use
- Sticking calipers or corroded components
- Brake fluid issues impacting performance
Because regen braking limits conventional brake use, it’s easy to overlook physical wear—making inspection all the more important.
3. Tyre Wear and Pressure
EVs are generally heavier due to battery packs and deliver instant torque. This can cause faster tyre wear, especially on the front wheels.
Routine checks may reveal:
- Uneven tread wear due to suspension imbalance
- Low pressure impacting efficiency and safety
- Tyres unsuitable for load rating or torque output
Choosing the right tyres and maintaining correct inflation improves both handling and battery range.
4. Steering and Suspension
The added weight of an EV and instant torque delivery can place stress on suspension and steering components. Over time, even small issues can affect safety and comfort.
Servicing may highlight:
- Premature bushing or joint wear
- Steering misalignment
- Noise or vibration on rough roads
Addressing these early maintains driving performance and extends component lifespan.
5. Software and Diagnostics
Many EV problems begin as subtle software glitches or sensor misreads. Diagnostic checks during an MOT and service appointment can pick up fault codes, update firmware, and reset systems to manufacturer standards.
This also helps ensure compatibility with the latest safety features and charging infrastructure.
Why Ongoing Checks Matter—Even for New EVs
It’s a common misconception that new EVs don’t require maintenance. In fact, regular inspections from year one can:
- Preserve battery health and charging consistency
- Prevent minor faults from becoming major failures
- Ensure the vehicle meets safety and roadworthiness standards
Even EVs must pass an MOT after three years. Combining your MOT with a professional service gives you a full picture of your car’s condition and can prevent warranty issues down the line. Booking an MOT and service at the same time ensures both legal compliance and peace of mind.
The Future is Electric and Reliable
EVs are paving the way for a cleaner driving future, but they still require care and attention to stay reliable. By understanding what regular checks can reveal and making them part of your routine, you’ll maximise your EV’s lifespan, safety, and efficiency.
Whether you’re a new EV owner or a seasoned electric driver, one thing is clear: a well-maintained vehicle isn’t just better for your journey. It’s better for your wallet and the planet too.
